| 摘要: |
| 本文基于InVEST模型，以连云港市赣榆区为例，从固碳释氧、水质净化、生物多样性和水资源供给4项服务进行生态功能重要性评价分区，定量识别该区重要生态功能区，评价结果表明，赣榆区重要生态功能区总面积为383.06km2，占全区总面积的25.93%，其中：生态系统服务高值区面积8.24km2，中值区面积为82.13km2，低值区面积为292.69km2，初步构建了赣榆区生态安全格局，促进本区生态系统保护与社会经济发展相协调。在此基础上，结合赣榆区农业发展现状，对三级重要生态功能区保护及全区农业开发利用提出建议，可为赣榆区优化国土空间格局、推进生态文明建设提供参考。 |

| Abstract: |
| This paper takes Ganyu District, Lianyungang City (a hilly area in eastern Jiangsu) as an example to evaluate the importance of ecological functions in four services, namely carbon fixation and oxygen release, water purification, biodiversity and water resource supply, quantitatively identify the key ecological function zones in the study area, and put forward suggestions for protection and restoration of these zones. The evaluation results showed that the total area of important ecological functional zones in Ganyu District was 383.06 km2, accounting for 25.93% of the total area of Ganyu District. Among them, the area of high-value ecosystem service was 8.24 km2, the area of median ecosystem service was 82.13 km2, and the area of low-value ecosystem service was 292.69 km2. Its ecological security pattern has been preliminarily established, which is conducive to its construction of ecological security guarantee and the coordination between its ecological system protection and social and economic development. |
